The NRA argument is mostly great: the only way to stop a bad guy with a gun IS a good guy with a gun. Who that exactly is should be left to each school district to decide on it's own. Localized control is always better than top down dictate from the State capital, much less DC. It may be private security or armed staff or it may be a teacher with a CCW. Certainly not EVERY single teacher needs to be armed. Just enough to make a potential mass murderer think twice if not one that could actually put him down. Sandy Hook could have been stopped if the Principal alone had been armed. Certainly an armed security could have responded once the Principal was shot, if not when he entered the building (by shooting the glass door).

Everything else, from video games to the civil rights angle is a distraction to that very simple fact on larger social and civil issues. NRA should keep it's focus simpler and on a tighter focus and use an eloquent spokesman who doesn't need to be the head of the organization. Chuck Woolery, etc would be perfect.
